Do You Want to Build a Snowpony?

We used to be best buddies...now we're not, I wish you'd tell me why.

Sweetie Belle and Rarity are as close as sisters can be...or at least, they used to be. Lately, Rarity has been too busy for Sweetie Belle. She's tried to get through to her sister, but nothing Sweetie Belle does gets through to Rarity. Her sister can't even take time off to build a snowpony with her sister anymore.

Inspired by the song from Frozen.
